Do some of the pages may not receive any page rank rather than just being diluted to the point of not being worthwhile?
JOHN MEULLER (Webmaster Analyst from Google):
At least from a technical point of view, we kind of have to split up the page rank that these pages get among the links that are there. And if you have a really, really high number of links, then that might result in us not actually forwarding that much useful page rank to those individual links. And if these pages aren’t linked anywhere else on the website, then what might happen is we end up not crawling them as frequently. We maybe don’t crawl them at all if we kind of run out of time to actually look at pages that were discovered on the site. So that’s essentially what can happen there. If there are other ways to get to this content, I’m sure we’ll try to find ways to do that as well. So it’s kind of like when you have an e-commerce website. You tend to set up categories that have a reasonable number of individual product links on a page or that have subcategories linked on that page. If you have hundreds and hundreds of product links on a category page on an e-commerce site, then from a usability point of view, it’s really hard to use. And from understanding the site itself, it’s really hard for us to figure out which of these individual product pages actually belong to which category and how relevant are they for these pages. Is it maybe one important page for this category, or is this one out of 2,000 different things that are on this category page?
